CROSS-REFERENCE TO RELATED APPLICATIONS

This application is a continuation application of PCT Application No.PCT/CN2019/085814 filed on May 7, 2019, which claims priority to ChinesePatent Application No. 201810450841.0, filed in China on May 11, 2018,disclosure of which are incorporated herein by reference in theirentireties.

TECHNICAL FIELD

Embodiments of this disclosure relate to the communications field, andin particular, to a method for processing a CSI processing unit, anapparatus, and a system.

BACKGROUND

In a communications system, user equipment (UE) may send a channel stateinformation (CSI) report to a base station, so that the base station canobtain CSI based on the CSI report and schedule the UE based on the CSI.

Usually, the base station may configure a reference signal resource (forexample, a CSI reference signal (CSI-RS) resource) for the UE orindicate a reference signal resource to the UE, so that the UE performsCSI measurement. After the UE obtains the reference signal resourceconfigured or indicated by the base station, the UE may allocate a CSIprocessing unit to the reference signal resource, so that the UEperforms a measurement process on the reference signal resource. Aftermeasuring the reference signal resource, the CSI processing unit mayprocess (for example, calculate or analyze) a measurement result andgenerate a CSI report based on a processed result, and then the UE sendsthe CSI report to the base station.

However, when a cell on which the UE camps is deactivated, or abandwidth part (BWP) in which the UE works is switched, according to theforegoing process, on one hand, because an occupied CSI processing unitcan perform a measurement process only on a reference signal resourceassociated with a CSI report corresponding to the CSI processing unit,the CSI processing unit cannot perform a measurement process on otherreference signal resources; on the other hand, because other resourcesrelated to this measurement process can be used only in this measurementprocess, these resources cannot be used in other processes. Therefore,resources (including the foregoing CSI processing unit and otherresources) in the measurement process of the UE are wasted, andutilization of the resources in the measurement process of the UE isreduced.

In the embodiments of this disclosure, terms such as “exemplarily” or“for example” are used to represent examples, illustrations, orexplanations. Any embodiment or design solution described as“exemplarily” or “for example” in the embodiments of this disclosureshall not be interpreted to be more preferential or advantageous thanother embodiments or design solutions. Specifically, the terms such as“exemplarily” or “for example” are intended to present related conceptsin a specific manner.

The following describes some concepts and/or terms used in a method forprocessing a CSI processing unit, a resource processing method, anapparatus, and a system provided in the embodiments of this disclosure.

CSI: namely channel state information. The CSI may include at least oneof a channel quality indicator (CQI), a precoding matrix indicator(PMI), a CSI-RS resource indicator (CRI), a layer indicator (LI), a rankindicator (RI), and L1-reference signal received power (RSRP).

Periodic CSI report: It may refer to a CSI report periodically sent byUE to a base station. Specifically, a radio resource control (RRC) layermay configure parameters (for example, a period, a slot offset, and asymbol in a slot) of a periodic CSI report, and then the UE may transmitthe periodic CSI report based on the parameters of the periodic CSIreport by using an uplink control channel (for example, a long/shortphysical uplink control channel (PUCCH).

Aperiodic CSI report: It may refer to a CSI report sent by the UE to thebase station based on an indication of the base station (for example,when receiving indication information sent by the base station).Specifically, the RRC layer may configure parameters (for example, aslot offset and a symbol in a slot) of an aperiodic CSI report, and thenafter the UE receives downlink control information (DCI) sent by thebase station, the UE transmits the CSI report by using an uplink datachannel (for example, a physical uplink shared channel (PUSCH)). Forexample, the CSI report may include reports on a plurality of componentcarriers and a plurality of types of reports (beam measurement reportand CSI measurement report).

Semi-persistent CSI report: After the RRC layer configures parameters(for example, a period, a slot offset, and a symbol in a slot) of asemi-persistent CSI report, the UE may send the semi-persistent CSIreport based on an indication (for example, activation or deactivation)of MAC CE signaling by using an uplink control channel; and/or after theUE receives DCI sent by the base station, the UE may send thesemi-persistent CSI report by using an uplink data channel.

Bandwidth part (BWP): A cell served by the base station supports a largebandwidth (hereinafter referred to as the large bandwidth), but the UEmay work in a plurality of small bandwidth parts (hereinafter referredto as the small bandwidth parts). A small bandwidth part in which UEwithin the large bandwidth can work is referred to as a BWP. Each BWPcorresponds to a Numerology, a bandwidth, a frequency location(frequency location), and the like. Each BWP may include three controlresource sets (CORESETs).

In the embodiments of this disclosure, it may be understand that a celland a carrier are a same concept. Specifically, a carrier may be acarrier corresponding to a cell. For example, activating a cell may beunderstood as activating a carrier corresponding to the cell, anddeactivating a cell may be understood as deactivating a carriercorresponding to the cell.

The embodiments of this disclosure provide a method for processing a CSIprocessing unit, a resource processing method, an apparatus, and asystem. After UE receives first signaling sent by a base station, whentarget information (the target information includes at least the firstsignaling) satisfies a preset condition, the UE may process a first CSIprocessing unit by using a first processing manner corresponding to thetarget information. When performing a measurement process, the UE maydetermine different first processing manners based on different targetinformation. Therefore, for different target information, the UE canprocess the first CSI processing unit by using different firstprocessing manners, that is, the UE can control usage of the first CSIprocessing unit based on an actual requirement. Therefore, waste of CSIprocessing units in the measurement process of the UE can be reduced,and utilization of the CSI processing units in the measurement processof the UE can be increased.

In addition, after the UE receives first signaling sent by the basestation, the UE may process a first target resource by using a firsttarget processing manner. When performing a measurement process, the UEmay process the first target resource by using different first targetprocessing manners. Therefore, the UE can control usage of resourcesbased on an actual requirement. Therefore, waste of resources in themeasurement process of the UE can be reduced, and utilization of theresources in the measurement process of the UE can be increased.

The method for processing a CSI processing unit, the resource processingmethod, the apparatus, and the system provided in the embodiments ofthis disclosure may be applied to a communications system, andspecifically, may be applied to resource processing in the measurementprocess of the UE based on the communications system.

For example, FIG. 1 is a schematic architectural diagram of acommunications system according to an embodiment of this disclosure. Asshown in FIG. 1, the communications system may include UE 01 and a basestation 02. A connection may be established between the UE 01 and thebase station 02.

It should be noted that in this embodiment of this disclosure, theconnection between the UE 01 and the base station 02 shown in FIG. 1 maybe a wireless connection. To indicate a connection relationship betweenthe UE 01 and the base station 02 more clearly, a solid line is used inFIG. 1 to indicate the connection relationship between the UE 01 and thebase station 02.

The UE is a device that provides a user with voice and/or dataconnectivity, for example, a handheld device with a wired or wirelessconnection function, or another processing device connected to awireless modem. The UE may communicate with one or more core networkdevices by using a radio access network (RAN). The UE may be a mobileterminal, for example, a mobile phone (or referred to as a “cellular”phone) and a computer having a mobile terminal, or may be a portable,pocket-sized, handheld, computer built-in, or in-vehicle mobileapparatus, which exchanges voice and/or data with the RAN. For example,the UE is a device such as a personal communication service (PCS) phone,a cordless telephone set, a Session Initiation Protocol (SIP) phone, awireless local loop (WLL) station, or a personal digital assistant(PDA). The UE may also be referred to as a user agent, a terminaldevice, or the like.

The base station is an apparatus deployed in the RAN and configured toprovide a wireless communication function for the UE. The base stationmay include a macro base station, a micro base station, a relay station,an access point, and the like in various forms. A device with a basestation function may have different names in systems using differentradio access technologies. For example, the device is referred to as aNodeB in a third generation mobile communications (3G) network, orreferred to as an evolved NodeB (eNB or eNodeB) in an LTE system.

The method for processing a CSI processing unit, the resource processingmethod, the apparatus, and the system provided in the embodiments ofthis disclosure are hereinafter described in detail with reference tothe accompanying drawings by using specific embodiments and applicationscenarios thereof.

It should be noted that the method for processing a CSI processing unitand the resource processing method provided in the embodiments of thisdisclosure are hereinafter separately described in detail by using twospecific embodiments (that is, Embodiment 1 and Embodiment 2).

Embodiment 1

Based on the communications system shown in FIG. 1, this embodiment ofthis disclosure provides a method for processing a CSI processing unit.As shown in FIG. 2, the method for processing a CSI processing unit mayinclude the following step 201 to step 203.

Step 201: A base station sends first signaling to UE.

In this embodiment of this disclosure, the first signaling may be usedto instruct to deactivate a first cell that provides a service for theUE, or used to instruct the UE to switch from a source BWP to a targetBWP.

In this embodiment of this disclosure, the first cell may be a cell thatserves the UE.

Optionally, in this embodiment of this disclosure, the first signalingmay be cell deactivation signaling or BWP switching signaling, where thecell deactivation signaling is used to instruct to deactivate the firstcell, and the BWP switching signaling is used to instruct the UE toswitch from the source BWP to the target BWP.

Optionally, in this embodiment of this disclosure, the BWP switchingsignaling may be used to instruct the UE to perform uplink BWPswitching, or used to instruct the UE to perform downlink BWP switching,or used to instruct the UE to perform uplink BWP switching and downlinkBWP switching. The BWP switching signaling used to instruct the UE toperform uplink BWP switching may be applied to a frequency divisionduplex (FDD) system. The BWP switching signaling used to instruct the UEto perform downlink BWP switching may also be applied to the FDD system.The BWP switching signaling used to instruct the UE to perform uplinkBWP switching and downlink BWP switching may be applied to a timedivision duplex (TDD) system.

Optionally, in this embodiment of this disclosure, when the base stationdetects great interference (for example, the interference is greaterthan a first preset threshold), poor signal quality (for example, signalstrength is less than a second preset threshold), and/or no service ofthe UE within preset duration in the first cell, the base station maysend the first signaling (for example, the cell deactivation signaling)to the UE, so that the base station and the UE deactivate the firstcell.

Optionally, in this embodiment of this disclosure, the base station maysend RRC signaling or DCI to the UE, to instruct the UE to switch fromthe source BWP to the target BWP, where the RRC signaling carries thefirst signaling (for example, the BWP switching signaling), and the DCIcarries the first signaling (for example, the BWP switching signaling).

For example, the base station may send DCI carrying the BWP switchingsignaling to the UE, to instruct the UE to switch from the source BWP(for example, a first CORESET in the source BWP) to the target BWP (forexample, a second CORESET in the target BWP).

It may be understood that before the UE switches from the first CORESETto the second CORESET, the source BWP in which the first CORESET islocated is a BWP in an active state; and after the UE switches from thefirst CORESET to the second CORESET, the target BWP in which the secondCORESET is located is a BWP in an active state.

Step 202: The UE receives the first signaling sent by the base station.

Step 203: When target information satisfies a preset condition, the UEprocesses a first CSI processing unit by using a first processing mannercorresponding to the target information.

In this embodiment of this disclosure, the target information includesat least the first signaling, the first CSI processing unit is a CSIprocessing unit for measuring a first downlink reference signalresource, and the first downlink reference signal resource is a downlinkreference signal resource in the first cell or the source BWP.

In this embodiment of this disclosure, in a measurement process of theUE, after the UE receives first signaling, the UE may determine thetarget information, and determine whether the target informationsatisfies the preset condition; and when the UE determines that thetarget information satisfies the preset condition, the UE may processthe first CSI processing unit by using the first processing mannercorresponding to the target information.

In this embodiment of this disclosure, after the UE receives the firstsignaling sent by the base station, the UE may determine the targetinformation based on the first signaling.

Optionally, in this embodiment of this disclosure, the first downlinkreference signal resource may be a downlink reference signal resource inthe first cell, and the downlink reference signal resource in the firstcell may include at least one of a channel state information-referencesignal (CSI-RS) resource in the first cell, a channel stateinformation-interference measurement (CSI-IM) resource in the firstcell, a synchronization signal block (SSB) resource in the first cell,and a zero power (ZP) CSI-RS resource set in the first cell.

Optionally, in this embodiment of this disclosure, the first downlinkreference signal resource may be a downlink reference signal resource inthe source BWP, and the downlink reference signal resource in the sourceBWP may include at least one of a CSI-RS resource in the source BWP, aCSI-IM resource in the source BWP, an SSB resource in the source BWP,and a ZP CSI-RS resource set in the source BWP.

For example, the CSI-RS resource may be a semi-persistent CSI-RSresource, the CSI-IM resource may be a semi-persistent CSI-IM resource,and the ZP CSI-RS resource set may be a semi-persistent ZP CSI-RSresource set.

It should be noted that the target information and the targetinformation satisfying the preset condition are described in detail inthe following embodiment and not described herein.

It should be noted that in this embodiment of this disclosure, measuringthe first downlink reference signal resource by the first CSI processingunit may be understood as performing a measurement process on the firstdownlink reference signal resource by the first CSI processing unit,where the measurement process may be that the first CSI processing unitmeasures the first downlink reference signal resource, processes (forexample, calculates and analyzes) a measurement result, and thengenerates a CSI report based on a processed result.

In the method for processing a CSI processing unit according to thisembodiment of this disclosure, after the UE receives the first signalingsent by the base station, when the target information (the targetinformation includes at least the first signaling) satisfies the presetcondition, the UE may process the first CSI processing unit by using thefirst processing manner corresponding to the target information. Whenperforming the measurement process, the UE may determine different firstprocessing manners based on different target information. Therefore, fordifferent target information, the UE can process the first CSIprocessing unit by using different first processing manners, that is,the UE can control usage of the first CSI processing unit based on anactual requirement. Therefore, waste of CSI processing units in themeasurement process of the UE can be reduced, and utilization of the CSIprocessing units in the measurement process of the UE can be increased.

Optionally, in this embodiment of this disclosure, with reference toFIG. 2, as shown in FIG. 3, after the foregoing step 202, the method forprocessing a CSI processing unit according to this embodiment of thisdisclosure may further include the following step 301.

It should be noted that in this embodiment of this disclosure, releasingmay be understood as non-occupying. For example, releasing the first CSIprocessing unit by the UE may be understood as no longer occupying thefirst CSI processing unit by the UE.

In this embodiment of this disclosure, when the target informationincludes the first signaling, the first signaling is the type-1signaling, and the type-1 signaling is the cell deactivation signaling,the UE may release the first CSI processing unit. Therefore, waste ofthe first CSI processing unit in the measurement process of the UE canbe reduced, and utilization of the first CSI processing unit in themeasurement process of the UE can be increased.

Therefore, it can be ensured that the measurementprocess is normally completed, while the first CSI processing unit isnot wasted.
